python - TclError matplotlib 1.5.0

Question

使用下面的代码，生成一个 TclError。

import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt

plt.plot([1,2,3,4], [1,4,9,16], 'ro')
plt.axis([0, 6, 0, 20])
plt.show()

当我在终端中执行我的脚本时，我得到以下信息:

/Users/<username>/anaconda/lib/python2.7/site-packages/matplotlib/__init__.py:1035: UserWarning: Duplicate key in file "/Users/<username>/.matplotlib/matplotlibrc", line #2

TclError

是什么导致了这个错误？我尝试将 backend: TkAgg 添加到我的 matplotlibrc 文件中，但无济于事。

请指教

想通了:

而不是使用:

matplotlib.use('TkAgg')

使用:

matplotlib.use('Qt4Agg')

或任何其他后端
